Best: May-Jun, Aug-Sep · Great: Jul
Rain is a non-factor here almost every month — the real story of the year is temperature, swinging from January's cooler stretch to July's peak heat. In September, expect highs around 25°C with rain on roughly 1 day of the month.
Isfahan's grand squares and mosques and Shiraz's gardens and poetry heritage are the country's cultural highlights, and Nowruz (Persian New Year, late March) is the biggest festival.
Try Persian kebabs, saffron rice (tahdig), and fresh herb-forward stews.
